VENTILATOR ATTACHMENT FOR WATER-CLOSET BOWLS- SPEGIFICA'IION forming part of Letters Patent N 0. 776,815, dated December 6, 1904.

Application filed September 13,1902. Serial No. 123,214. (No model.)

1'0 (Mt w/wm/ it may concern:

Be it known that we, CI-IARLEs A. SULLIVAN and PETER J. SWEENEY, residing at I/Vindsor, in the county of Essex, Province of Ontario, Canada, and EDWARD J .Woo msoN, residing at Detroit, county of Wayne, State of lVIichigan, citizens of the United States, have invented a certain new and useful Improvement in Ventilating Attachments for ater-Closet Bowls; and we declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to ventilators, and has for its object an improved ventilating attachment to be used with the bowls of waterclosets.

In the drawings, Figure l is a plan view of the ventilator made integral to the bowl. Fig. 2 is a View looking upward toward the under side. Fig. 3 is a vertical longitudinal section of one end of the ventilator. Fig. 4 is a cross-section at the line a; of Fig. 3. Fig. 5 is a cross-section at the line 1 3 of Fig. 3. Fig. 6 shows a detachable ventilator. Fig. 7 is a perspective showing the air-discharge pipe employed with a detachable ventilator. Fig. 8 is a perspective showing the detachable ventilator in reversed position.

For structural reasons the detachable ventilator is made in two parts P and 1%. Each part consists of a curved or bent tube of about a quadrant with the end g (or 9) provided with an adjustable spray-controller and the ends 8 8 arranged to telescope or engage one within the other. A discharge-pipe t is attached to one of the parts.

30 indicates a water-supply pipecurved to correspond with the two sections P and R of the spray-pipe connected with a source of water-supply by feed-pipe 31, in which there is a valve 32, arranged to be actuated by the seat. One branch of the water-supply pipe 30 terminates under the end 9 of the spraypipe and the other branch terminates under the end g. In each case it leads into a chamher which is similar in function to the chamber of the fixed ventilator particularly here- 5 inafter described. The air-outlet from the chamber through a pipe t, that leads to the ventilator-pipe 25.

The fixed attachment has a chamber constructed in the material oi? which the bowl is made. The ends are open for the insertion of nozzle-holders Z) 7), and into these nozzleholders lead the terminals from water-supply pipe 2, that connects with a source of watersupply through a pipe in which there is a seat-actuated valve/l.

The nozzle-holder 7) comprises a casing 11, in which spray-valve 7 engages in an orifice 6 and is provided with a stem 8, which passes through a guide bar or spider 9 and also 5 wayas, 't'or example,by inserting the end of 7 the water-supply pipe 2 through the walls of the chamber in the casing 11. The end of the stem 8 projects beyond the end 10 of the casing and is threaded and provided with an adjusting-nut 13, and spring 14 is arranged to hold the valve 7 in proper position with re spect to the orifice 6.

The valve 7 does not seat on the walls of the orifice, but is capable of adjustment to close down the annular opening between the valve and the walls of the orifice to an extremely thin line, or it may be adjusted to increase the annular opening by turning the thumb-nut 13 and moving the valve to the proper adjustment. by the gathering of sol-id material in the thin opening the valve may be drawn back forcibly at any time against tension of spring 14:, and the water will at once cleanse the edges of the valve and the orifice. the chamber 5 passes through the thin ope11 ing between the valve 7 and the walls of the orifice 6 in a thin stream or spray, which spreads as the distance from the orifice increases and carries with it air drawn in by siphoning action through openings 15 and 16 in the walls of the spay-chamber.

In the spray-chamber about midway be- In case of obstruction to the orifice 5 Water entering 9 tween the ends A and B are interposed a number of baffle-screens 17 18 19. Each screen consists of a plate 20, that extends partially across the spray-chamber, and a screen 21, that extends the remainder of the distance across the chamber. Between the baflle-plates and on the spray side of them are small openings through the under side of the walls of the spray-chamber for the discharge of water into the bowl underneath the spray-chamber.

The air after passing the baflie-plates is allowed to have egress from the spray-chamber through a pipe 23 and connects by ordinary piping to exhaust-pipe 25.

There need be only one exit-pipe to the two spray-chambers. At the rear of the spraychamber there are outlet-holes opening downward, (shown at 26 in Fig. 2,) which furnish outlet for any water that may have traveled thus far.

The detachable attachment can be located wholly within the bowl, where it is practically out of sight, having no external connections except the pipe leading to the exhaust and the small water-pipe leading into the bowl. It is held in place by hangers 27, that are simple hooks engaging over the edge of the bowl and under the attachment at proper places to sustain it in its position.

Vhat we claim is- 1. A ventilator for closet-bowls comprising a spray-chamber arranged to empty directly into the bowl, water and air connections, and means interposed between the spray and the exit for impeding the free passage of water along the spray-chamber, substantially as described.

2. A ventilating attachment for closetbowls, comprising a spray-chamber, provided with a plurality of openings along its length arranged to empty directly into the bowl, water and air connections, means for impeding the free travel of the water along the chamber, and means for hanging the spray-chamber inside the closet-bowl, substantially as described.

3.'In a ventilating attachment for closetbowls, the combination of a bent pipe provided with spray-water-inlet openings at each end, air-inlet openings near each end, and

Water-outletopenings opening downward intermediate the ends, substantially as described.

4. In a ventilating attachment for waterclosets, the combination of a spray-chamber provided with openings for the outflow of water therefrom arranged at intervals along the floor of the chamber, a spray-nozzle at the end thereof, means for adjusting the spraynozzle, substantially as described.

In testimony whereof we sign this specification in the presence of two witnesses.
